There is a new MSN bug that I've never seen before that has occured. Try going to www.msn.com and typing the query, for example: United Health
Now, click on Page 2 of the results on the bottom right corner. MSN redirects you automatically to page 3, and you aren't able to view page 2 results at all!
I have tried testing this on multiple computers and asked others to try it out and am still getting the same result.
